Long-term exposure to high levels of
manganese can cause problems with the central nervous system. Exposure can result from inhalation of dust or fumes. The resulting disease is called manganism. Its symptoms include, but may not be limited to, weakness,
lethargy,
speech disturbances, a mask-like face,
paralysis,
tremors, and
psychological disturbances.
